Do you play as your Simself?

My simself is very close to me in appearance, personality, and hobbies, but also infinitely more competent at everything she does than I am, and has things in her life that I wish I had. So my ideal answer would be a mix of the first two options: A realistic representation of me in a simulated life not unlike reality, but with a bit of "what if" thrown in here and there.

Oh, and it's the same for my entire family. They're all in my game, too.
